Correction to: Nested plant LTR retrotransposons target specific regions of other elements, while all LTR retrotransposons often target palindromes and nucleosome-occupied regions: in silico study.

Following publication of the original article [1], the authors spotted an error in Table 2.

Table 2

Palindromes within sequences flanking the insertion site. We used the paldpl program to detect approximate palindromes of at least 3 bp with no more than 30% mismatches or indels. This analysis was done in native flanking sequences identified in plant genomes and their randomized (permutated) counterparts, to control for base content effects. We carried out a paired t-test for difference in calculated stem lengths of the native and randomized palindromes. Significant values after Benjamini-Hochberg correction for multiple family testing are marked with an asterisk and printed in bold (* for p < 0.1, ** for p < 0.01 and *** for p < 0.001). Three families with increased mean palindrome stem length after randomization are marked with a tilde

t-test pvalue in penultimate row = “0.61” should not be bold

the asterisks with significance levels should be as follows: “(* for p < 0.1, ** for p < 0.01 and *** for p < 0.001)”
